Its a great way to save genetics where a clone dies on you. I have done it a couple times and had great luck with it. I can give you a couple hints doing a reveg.
1st, understand that flowering plants and vegging plants have different types of roots. Most strains will stop producing new roots a bit after the stretch is over. The plant is dedicating its energy into the flowers like we want it to do. But when you are going to reveg, you have to get the plant to start producing roots again.
How does one do that? Easy peasy. Switch your plant back to an 18-6 light schedule for its last 10-14 days of flower. This will not effect your meds at all unless you have a very fast revegging plant. If by chance, you see any new growth start to shoot out of your buds, its time to chop. Otherwise just harvest at normal time and leave 5 or 6 lower nugs with as many leaves on them as possible to finish your reveg.
Keep it at 18-6 as it continues to go through its transition into growing vegging roots again. Pretty soon it will start throwing out a bunch of funky new growth. Most of it will likely have 1 or 3 finger fan leaves for a couple weeks.....but when she explodes with new growth it will be crazy vigorous......called a Monster Crop.
Usually when I see the new growth I will attempt to up pot to a bigger pot. Reveg's don't require nearly the veg time to produce a bumper crop that growing from clone or seed require. I pulled 10 ounces of a Hawaiian in an 8 gallon pot, did the reveg in the same pot and didn't up pot at all (just top dressed twice and did a couple ACTs) and I yielded another 8 ounces from the same plant. I could have easily pulled more if I would have up potted to a bigger pot with fresh soil. I know of people that have revegged the same "frame" of a plant 3-4 times and the yields have gone up each time.
Play around with the process...you never know when you will need it. I'm gonna do it again in about another week with a Gorilla Glue #4 plant. The clone I took didn't make it and I didn't feel like doing a clone that needed to reveg......so I'll throw her back under 18/6 on the 1st of the month (Day 44 of flower) and then harvest her about day 55-58. Its in a 5 gallon pot right now....I figure after she successfully reveg's I will up pot to a 10 gallon pot, give her about 4-6 weeks to fill out the frame and then take clones and flip her again.
One warning again, watch for new growth when you begin the reveg process. I have seen new growth happen in less than 10 days on quick strains. As soon as you see any leaves starting to come out of any of the bud sites, that is your queue to harvest any buds you intend on taking....otherwise the reveg will ruin the buds you intend to harvest if you don't chop quickly.
SO why not just run it at 12-12 til harvest? Well you can, and I have.....and it can work, but its not nearly as effective or guaranteed as if you do what I described above. The reason be is if you wait until the plant has put all its energy into the buds and they are nice and ripe......it quite possibly won't have the steam to do the root reveg. I have seen plants just putter out and die during the reveg process cause they weren't put back under 18-6 or 20-4 or even 24-0 in time to signal the roots to start growing again.
From personal experience, the reveg works much better with a much higher success rate if you switch lighting 10-14 days out from the intended harvest time. Take the info for what its worth. If you have any other questions about the process, let me know.
There is a decent book out there about revegging.....I believe the Author is JB Haze. Its worth checking out if you want to learn more about the process.
In regards to fungus gnats. Their damage can look a lot like deficiencies. Some of those leaves look like they could have been from the stress of the fungus gnats. They start chowing on the roots and the plant will show signs with yellowing and brown spots. Don't always assume its a nutrient deficiency if you are showing pests. Pests damage will be displayed on leaves for you to see.
Thanks for the advice. I still have about 4 weeks on these so we'll see what I decide to do in the next couple weeks. I have the mother in another tent and she is about 2 1/2 weeks ahead. I wanted to test that one before I wasted my time and space on a reveg project. I will look into the book though thanks.
These plants all take about 3 days to dry out and they are all due for a top dressing on the next feeding which will be tomorrow some time so hopefully that will fix the problem. There aren't anymore gnats in the traps after 2 days so hopefully they are all gone. I definitely don't want to freak out and do too much at once. So we'll see how the plants react to the next feeding and go from there.
